What’s the best way to talk to the neighbors at an open house to find out if the street is ok?

What’s the best way to talk to the neighbors at an open house to find out if the street is actually loud or annoying at night? I don\'t want to be a huge creep. Ha! I also want the neighbors to be honest. I get that they might not want to share all the dirty secrets of the street with a stranger. So, how do I go about this?
